Description
Technical Field
the invention relates to the technical field of agricultural planting, in particular to a method for repairing continuous cropping obstacle soil of tobacco and vegetables.
Background
Tobacco is one of important economic crops in China, and has very important effect on the development of local economy. Continuous cropping and rotation are main farming modes for tobacco cultivation in China, scientific and reasonable rotation is beneficial to stabilizing and improving the quality of tobacco leaves, and continuous cropping and unreasonable rotation (relative to tobacco leaf production) can cause the quality of tobacco leaves to be reduced and other problems. Tobacco experts at home and abroad always pay more attention to the research on the cultivation crop rotation mode of tobacco, and the tobacco is not suitable for crop rotation with vegetables.
However, in the actual tobacco production, a tobacco-vegetable or sweet potato economic crop-tobacco rotation mode is adopted in a considerable part of tobacco fields, and the mode is that after the harvest of tobacco leaves in the current season is finished, economic crops such as vegetables and sweet potatoes with short growth period are planted, and the tobacco leaves are ploughed and ridged until the next flue-cured tobacco suitable transplanting season, and then the flue-cured tobacco is planted.
in the actual tobacco production, the mode is found to bring many adverse factors to the tobacco production, such as aggravation of diseases, reduction of the quality of the tobacco, difficulty in nitrogen nutrition regulation, unbalance of the nutrients of tobacco planting soil and the like.
A part of tobacco fields adopt a spring flue-cured tobacco-vegetable rotation mode in successive years, and the flue-cured tobacco has serious continuous cropping obstacles after one or two years of rotation. The continuous cropping obstacle of the flue-cured tobacco is caused by the obstacle of the continuous cropping soil of the tobacco and the vegetable, so that the flue-cured tobacco planted in the soil does not grow roots and further the growth of the flue-cured tobacco is influenced. Therefore, the repair of the continuous cropping obstacle soil of the tobacco and the vegetable is necessary for ensuring the production and development of the tobacco and the vegetable in the area.
The current methods for repairing continuous cropping obstacle soil mainly comprise: 1) changing dry farming into water farming; 2) sterilizing soil; 3) applying microbial organic fertilizer. The first method is not adopted by tobacco growers due to low economic benefit of planting rice; the second method is influenced by overhigh input cost to be popularized and used; the effect is unstable by using the third method alone, so that the method is not acceptable.
